Piezoelectric Effect: The quartz crystal used in the ring is carefully cut and oriented to maximize its piezoelectric response. When mechanical stress or pressure is applied to the crystal, it generates an electric charge across its surface. This effect is reversible, meaning that an applied electric field can also cause the crystal to deform or vibrate.
Applications: Piezoelectric quartz rings have diverse applications due to their ability to convert mechanical energy into electrical energy and vice versa. Some common applications include:
- Sensing and Measurement: Piezoelectric quartz rings can be used as sensors to measure various physical quantities such as force, pressure, acceleration, or vibration.
- Actuators: These rings can be utilized as actuators to generate precise and controlled mechanical movements in devices like inkjet printers, ultrasonic cleaners, or precision positioning systems.
- Frequency Control: Quartz rings are widely used in the manufacturing of quartz crystal oscillators, which are critical components in electronic devices for generating stable and accurate frequencies.
Size and Shape: Piezoelectric quartz rings can vary in size and shape depending on the specific application requirements. They are typically designed to be compact and can be integrated into various electronic devices.
Performance and Stability: Piezoelectric quartz rings offer excellent stability and precision in their electrical and mechanical response. They exhibit low hysteresis and high linearity, making them suitable for applications that demand accurate and reliable performance.
FAQs:
- Q: What are the products you mainly work on?
A: We look at ourselves as the piezo wafer specialist. We are the very first to work with Single Crystal Quartz in China about 30 years ago. Then gradually we step in the field of LiNbO3, LiTaO3, Quartz glass, LGS, CTGS etc. Especially, if you are looking for a piezo quartz supplier, we are the ultimate choice! We export millions of quartz blanks each year because we master the AT, SC and IT cuts with superior angle precision.
- Q: Can you accept product customization?
A: Yes, of course. We can fabricate as per your request. In addition, we are so experienced with piezo wafers that we can provide you relevant suggestions if you are not 100% sure about your choice. Besides, we do have some standard wafers in stock, please check with us.
- Q: Can we visit your factory?
A: Sure. Factory inspection is important for large quantity purchase and long-term cooperation. Face to face discussion is what we mostly confident with. During the past years, big names around the world have witnessed our progress in factory build-up. These days, due to the Covid-19 pandemic, we also had the experience of videoconferencing with global buyers.
